Pallet Cover Fumigation
Pallet cover fumigation refers to the process of fumigating goods that are stacked on pallets and wrapped or covered with a special material, often plastic or similar impermeable sheets, to create a sealed environment for the fumigation process. This method is commonly used in the transportation and storage of goods to ensure that they are free from pests, fungi, and other contaminants without the need to fumigate individual items separately.
01. Purpose of Pallet Cover Fumigation
Palletized cargo needs fast, reliable treatment that preserves speed of logistics while complying with national quarantine laws:
Pallet Pest Control
Eliminates active boring insects, beetles, and termites nested deep inside wooden pallet structural frames.
Fungal Prevention
Protects stacked boxes and contents from mold, rot, and decay caused by damp sea transit conditions.
High Efficiency
Fumigates large stacked batches together under one sheet, saving extensive cargo handling time.
02. Materials & Chemical Selection
- Hermetic Sheets: Polyethylene gas-barrier covers wrap completely over pallet stacks to prevent toxic chemical leakage.
- Methyl Bromide: Selected for quarantine treatments where rapid absorption and deep wood-borer termination is required.
- Phosphine: Deployed for dry agricultural pallets (coffee, nuts, bulk packages) sensitive to chemical residues.
- Sulfuryl Fluoride: Applied to electronic parts and specialized packages to prevent corrosion.
03. Standard Steps Involved
Our operations crew follows a strict sealing and monitoring layout for pallet treatments:
- Stacking Inspection: Cargo is stacked with adequate air gaps to ensure uniform gas distribution.
- Placing the Cover: The gas-barrier sheet covers the entire pallet stack down to the floor level.
- Bottom Sealing: The bottom edges of the polyethylene wrap are taped or weighted with sand snakes to lock in the gas.
- Gas Injection & Hold: Calculated gas amounts are introduced and held for the required exposure period.
- Ventilation & Safety Check: Covers are opened in ventilated zones, airing out cargo until gas monitors register clean air levels.
